‘Sometimes it feels as if the world goes on without me’: adolescents' experiences of living with chronic fatigue syndrome
2013
Aims and objectives To explore the experience of being an adolescent with chronic fatigue syndrome. Background Despite ample research, chronic fatigue syndrome is still poorly understood, and there are still controversies related to the illness. Adolescents with chronic fatigue syndrome are often unable to attend school and lose social relations with friends. The challenges they face will affect their quality of life. Design A qualitative, phenomenological hermeneutical design. Method Six boys and twelve girls, aged 12–18, were interviewed, emphasising their own experiences living with chronic fatigue syndrome. Analyses were performed using a phenomenological hermeneutical method. Results T…
Changes in the structure of the agonistic behavior of mice produced by D-amphetamine.
1997
The effects of three acute doses of D-amphetamine (0.25, 1.5 and 3 mg/kg) were studied in a model of isolation-induced aggression in male mice. An ethopharmacological analysis of the encounters was carried out, which studied the frequency, total and mean duration of different behavioral categories, including the temporal distribution of attacks and the duration of inter-attack intervals. The results show a reduction in the total and mean duration of the Attack category and an increase in motor activity manifested by longer durations, both total and mean, of Non Social Exploration and shorter Immobility. The temporal analysis of Attack revealed an increase in the number of very short (< 15 s…
Differential sensitivity to the effects of nicotine and bupropion in adolescent and adult male OF1 mice during social interaction tests.
2008
Few studies have compared the action of both nicotine (NIC) and bupropion (BUP), an antidepressant used to treat NIC dependence, on social and aggressive behavior at different ages. This study aims to determine whether these drugs produce differential effects in adolescent (postnatal day: 36–37) and adult (postnatal day: 65–66) mice that have been housed individually for 2 weeks in order to induce aggressive behavior. Mice received BUP (40, 20, or 10 mg/kg), NIC (1, 0.5, and 0.25 mg/kg as base), or vehicle earlier to a social interaction test. BUP (40 mg/kg) decreased social investigation and increased nonsocial exploration in both adolescent and adult mice. The same effects were also obser…
The Hikikomori Phenomenon of Social Withdrawal: An Emerging Condition Involving Youth's Mental Health and Social Participation.
2020
The objective of this editorial is to raise awareness on the burden and risks faced by adolescents developing this emerging form of social withdrawal. The hikikomori phenomenon is part of the group of new morbidities causing children and adolescents to limit their activity owing to a chronic health condition with attendant psychological problems. We further emphasize the importance of including new morbidities involving mental health and social participation in formal pediatric training, to enable new generations of pediatricians to identify and properly manage these disorders.
Association between osteoarthritis and social isolation: data from the EPOSA study
2019
Objective: To determine whether there is an association between osteoarthritis (OA) and incident social isolation using data from the European Project on OSteoArthritis (EPOSA) study.Design: Prospective, observational study with 12 to 18 months of follow-up.Setting: Community dwelling.Participants: Older people living in six European countries.Measurements: Social isolation was assessed using the Lubben Social Network Scale and the Maastricht Social Participation Profile. Clinical OA of the hip, knee, and hand was assessed according to American College of Rheumatology criteria. Demographic characteristics, including age, sex, multijoint pain, and medical comorbidities, were assessed.Results…
Social behavioural profile of cocaine in isolated and grouped male mice
2003
Studies concerning the relationship between cocaine and aggression in humans as well as in animals have discrepant outcomes. Increases, decreases, or no changes, have been reported after single or chronic cocaine administration in animal models. To clarify, at least in part, the complex behavioural actions of cocaine, the present study evaluated cocaine effects on social behaviours of mice exposed to different situations (isolated or group housed) using confrontations between two male mice in a neutral area. Different doses of cocaine (6, 25 and 50 mg/kg) were administered in a single or binge pattern (three doses in 24 h) and the behavioural test was performed 20 min after the last injecti…
Simplifying atrial fibrillation ablation: how far can we go?
2013
The procedural end point of electrical isolation of the pulmonary veins (PVs) for the treatment of atrial fibrillation (AF) has been debated extensively. After identifying the PVs as the dominant arrhythmogenic site of paroxysmal AF, 2 fundamentally different approaches to the interventional treatment of AF were introduced. Haissaguerre et al developed a technique to electrically isolate the PVs by targeting electrophysiological (EP) breakthroughs from the left atrium to the PVs guided by a circular mapping catheter. In contrast, Pappone et al implemented an anatomical approach that used circumferential ablation lines around the PVs guided by a 3-dimensional mapping system. This latter appr…
Riesgo de pobreza infantil y exclusión social en dos regiones españolas: determinantes sociales y familiares
2021
espanolObjetivo Describir el riesgo de pobreza y exclusion social en ninos/as de 8-11 anos de Gipuzkoa y Valencia (Espana), mediante los indicadores AROPE (At Risk Of Poverty or Social Exclusion), y evaluar sus factores asociados en el Proyecto INMA (Infancia y Medio Ambiente). Metodo Familias de Gipuzkoa y Valencia (394 y 382, respectivamente) completaron un cuestionario en 2015-2016. Se estimaron la baja intensidad de trabajo (BIT), el riesgo de pobreza (RP) y la privacion material (PM). AROPE consistio en cumplir cualquiera de estos subindicadores. Se consideraron caracteristicas sociodemograficas, familiares y parentales. Se usaron diagramas de Venn, los test de Ji-cuadrado y Fisher en …
Social withdrawal in children moderates the association between parenting styles and the children's own socioemotional development.
2014
Background: Social withdrawal in early childhood is a risk factor for later socioemotional difficulties. This study examined the joint effects of children’s social withdrawal and mothers’ and fathers’ parenting styles on children’s socioemotional development. Based on diatheses-stress, vantage sensitivity, and differential susceptibility models, socially withdrawn children were assumed to be more prone to parental influences than others. Methods: Teachers rated 314 children on prosocial skills, and internalizing and externalizing behaviors at three points in time between grades 1–3. Mothers (n = 279) and fathers (n = 182) filled in questionnaires measuring their affection, and their behavio…
Improving Isolation of Blindly Separated Sources Using Time-Frequency Masking
2008
A refinement technique based on time-frequency masking is proposed to improve source isolation in blind audio source separation algorithms. The refinement technique uses an energy-normalized source-to-interference ratio in order to identify and eliminate interfering energy from the extracted sources. Some examples using this refinement method with different separation algorithms are discussed. The results show that source isolation can be significantly enhanced with negligible degradation of the separated sources.
